Hacker Discovers Q and A Features In Google+ Code [readwriteweb.com]
A curious hacker named Matt Mastracci was diving into the Google Plus code yesterday, trying to turn on access to the new Circle-sharing feature, when he uncovered several new features apparently in the works. One, referred to in the source as "Google Experts," appears to be a Quora-like question and answer feature with the same posting, commenting and sharing features as regular Plus posts.
Mastracci also uncovered Google Voice integration, which will not require phone numbers; new photo browsing options including photos from Messenger; new, clearly labeled privacy presets and a feature like Facebook's wall, letting users post on each other's profile without showing up in others' streams.
